Jetbrains' IntelliJ IDEA is an intuitive, powerful and extremely intelligent IDE. It is used by many of your favorite open-source developers and projects (including warp).
If you would like a starter kit (extended full-functionality trial licenses). Feel free to send me an email at dhanji gmail com with your name, location and some information on what you do and how many licenses you are interested in. These licenses typically turn into discounts if you decide to purchase.
I do not have any professional or contractual relationship with Jetbrains s.r.o. Nor do I receive anything in return for promoting IntelliJ IDEA. Apart from a little peace of mind that one more programmer has been saved =)
